I would know the Moon's Age May the 12th, 1736; the Epact is 28, then the Sum of 28 and 3 and 12 is 43 ; subduct 30, the Re. mainder shews the Moon to be then 13 Days old; wherefore on the 14th of May will be the Full Moon ; and 15th before, viz. 29th of April, the Moon chang'd.

This was finish'd and first publish'd in the Year of our Lord 457. Afterwards, in the Year 527, Dionysius Exiguus, a The Dionysian Roman Abbot, corrected it in fome Particulars, Period. and it was calld the Dionysian Period from him ; as also the Great Paschal, because the Western Great Paschal.

He supposed the Excess of the Solar Year above the Lunar at the End of the Metonic Cycle of 19 Years, would in the Course of 4 of those Cycles, or 76 Years, amount to a whole Day, and so cast away a Day in every such Period of 76 Years.

This Period consists of 7980 Years, (for 28 by_19 gives 532 ; and that by 15 gives 7980.) This Period had its Beginning fix'd to the 764th Year before the Creation, and is not yet compleated ; and therefore comprehends all other Cycles, Periods, and Epochas, and the Times of all memorable Aitions and Histories. There is but one Year in the whole Period that has the same Numbers for the three Cycles of which it is made up : And therefore if Historians had remark'd in their Annals the Years of the respective Cycles, there had been no Dispute about the Time of any Action. The first Year of Christ was the 4714th Year To find the

principal Æra's are those of the Creation, of the
Olympiads among the Greeks, of the Building of

to the Years of the Julian Period, the Creation
of the World, and to the Years before and after
